Dynamic Audio Field of View Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mismatch between the field of view of visual content and the spatiality of audio content can be distracting and undesirable in image capture devices, leading to a suboptimal viewing experience.
Innovation Solution
A system that dynamically modifies audio content based on the variable field of view of visual content, using multiple sound sensors and a processor to generate modified audio content that matches the field of view, ensuring the audio aligns spatially with the visual content captured by the image capture device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If audio content is captured by multiple sound sensors to provide spatial audio, then the spatial coverage is improved, but the alignment between audio spatiality and visual field of view deteriorates
Solution Approach 1:
The patent applies local quality by processing audio signals differently based on their spatial origin relative to the visual field of view. Audio content captured within the field of view parameters is preserved and enhanced, while audio from outside the field of view is attenuated or removed. This creates a spatially differentiated audio output that locally matches the visual content boundaries, resolving the contradiction between maintaining broad spatial coverage and achieving precise alignment with the visual field of view.
Solution Approach 2:
The system dynamically changes audio parameters (spatial characteristics, volume, panning) based on the visual field of view parameters. By adjusting audio spatiality parameters to match the visual field of view angle and orientation, the system achieves precise alignment between audio and visual content while maintaining the benefit of multi-sensor spatial audio capture.
2Adaptability or versatility
If the field of view of visual content is adjusted to capture different scenes, then the visual versatility is improved, but the consistency between visual and audio spatial alignment deteriorates
Solution Approach 1:
The patent implements dynamics by making the audio processing parameters dynamic and responsive to changes in visual field of view. As the visual field of view adjusts to capture different scenes, the audio spatial processing dynamically adapts to maintain alignment. This dynamic coupling ensures that audio-visual spatial consistency is preserved across varying visual configurations, resolving the contradiction between visual versatility and audio-visual consistency.
Solution Approach 2:
The system uses feedback from the visual field of view parameters to control audio processing. The visual content's field of view information serves as feedback that adjusts the audio spatial characteristics in real-time, ensuring that audio remains aligned with the visual content regardless of how the field of view changes. This feedback mechanism maintains audio-visual consistency while allowing visual versatility.

AI summary
An image capture device may capture multiple audio content during capture of visual content. The field of view of the visual content may be used to generate modified audio content from the multiple audio content. The modified audio content may provide sound for playback of the visual content with the field of view.
